Question

Cellular respiration:

1) NADH is produced by this pathway.

2) The electron transport chain removes protons from which part of mitochondria?

3) ATP is produced in all stages of cellular respiration EXCEPT _____.

is this one glycolysis or pyruvate oxidation? If neither than i am very confused hah.

Answer 1

1.NADH is produced by glyvolysis, pyruvate oxidation and Citric acis cycle.

2. The electron transport chain is a series of electron transporters embedded in the inner mitochondrial membrane that shuttles electrons from NADH and FADH₂ to molecular oxygen. In the process, protons are pumped from the mitochondrial matrix to the intermembrane space, and oxygen is reduced to form water.

3. While the Krebs cycle does produce carbon dioxide, this cycle does not produce significant chemical energy in the form of adenosine triphosphate (ATP) directly.
